President Barack Obama has said he needs several days to determine how America will help Iraq deal with a militant insurgency, but he ruled out sending US troops back into combat.
Obama told a news conference he will explore "a range of other options" after key Iraqi towns and cities were seized by the Islamist militant group ISIS.
His cautious response today has prompted criticism and accusations that the US risks losing credibility.
ITV News Washington Correspondent Robert Moore reports:
The Foreign Secretary has been clear on the threat of Isis, but he has ruled out the prospect of any UK military involvement in the crisis.
Iraq’s foreign minister, Hoshyar Zebari, is a natural diplomat. Polite, immaculately dressed, and blessed with a great memory.
Isis has paraded military equipment in Mosul it captured from when the Iraqi army fled in what some see as a "nightmare scenario."
